FIELD OF THE INVENTION

The present utility model involves a fabric is woven by untwisted yarnsand twisted yarns.

BACKGROUND OF THE INVENTION

The untwisted yarns have many good features like softness, air porosityand hygroscopicity. Some clothes, which are woven by untwisted yarns,are comfortable. There has not been any untwisted yarn clothes for along time, because the tensile strength of the untwisted yarns is low.So the untwisted yarns are only manufactured into towels. In this areathe untwisted yarns are always being researched for making clothes, yetthere has been no one good untwisted yarn fabric in the market. Theuntwisted yarn fabric, which is researched by applicant at thebeginning, not only has some advantages but also has many disadvantagesin the practice. Disadvantages: the structure stability is not good; thestereoscopy, comfort and the strength all could not reach the higherrequirements.

SUMMARY OF THE INVENTION

The purpose of the present utility model is to provide a mixed fabricthat is woven by untwisted yarns and twisted yarns. Structure of themixed fabric has higher tensile strength. The clothes, which are madefrom the mixed fabric, have good structure stability, softness,permeability, stereoscopy, hygroscopicity and lower cost.

The present utility model could be realized through below technologyprograms. The mixed fabric, which is woven by untwisted yarns andtwisted yarns, contains warp yarns and weft yarns. The warp yarns arecomposed by the untwisted yarns and the twisted yarns, the weft yarnsare composed by the untwisted yarns and the twisted yarns. The twistedwarp yarns and the untwisted warp yarns are arranged one by one; thetwisted weft yarns and the untwisted weft yarns are arranged one by one.The twist factor of the untwisted yarns is below 200 after untwisting.The untwisted yarns are linear, and its fibers are parallel. The bulgyparts are formed on the surface of the fabric by arranging the untwistedyarns and the twisted yarns. The density of the fabric is between 60 and800 pieces per 10 CM. The diameter of the untwisted yarn is 1.1-5 timesthe size of the diameter of the previous twisted one, and the density ofthis fabric is between 200 and 480 pieces per 10 CM. The diameter of theuntwisted yarn is 1.1-2 times the size of the diameter of the previoustwisted one, and the density of this fabric is between 150 and 500pieces per 10 CM. If the twisted yarns are all warp yarns and theuntwisted yarns are all weft yarns, the quantity of the twisted warpyarns will be smaller than the quantity of the untwisted weft yarns; inother words, if the twisted yarns are all weft yarns and the untwistedyarns are all warp yarns, the quantity of the twisted weft yarns will besmaller than the quantity of the untwisted warp yarns. The twisted yarnsand the untwisted yarns are arranged one by one to form the warp yarns,the twisted yarns and the untwisted yarns are arranged one by one toform the weft yarns; the twisted yarns and the untwisted yarns arearranged one by one to form the warp yarns, the untwisted yarns are weftyarns; the twisted yarns and the untwisted yarns are arranged one by oneto form the weft yarns, the untwisted yarns are warp yarns, the twistedyarns are more than or equal to the untwisted yarns. The density of thefabric is between 220 and 400 pieces per 10 CM.

Advantages of the present utility model are good structure stability,stereoscopy and high tensile strength. Its softness, bulk, air porosityand hygroscopicity are better than all kinds of the present fabricshave. The weight of the present utility model is light, the surface issmooth. And its heat retention and the stronger affinity are good forour skin; moreover, its cost is relatively low. The present utilitymodel not only has the above advantages but also has crisp aestheticsthat we could use it to make clothes and beddings.

DETAILED DESCRIPTION OF THE INVENTION

The present utility model will be better understood from reading thedrawings.

The mixed fabric contains warp yarns and weft yarns. The warp yarns andthe weft yarns are not only twisted yarns but also untwisted yarns. Thetwisted yarn 4 intersects the untwisted yarn 3 at the point of theintersection, to form the bulgy part 2 on the surface of the fabric, soas to increase the stability of the fabric. The twist factor of theuntwisted yarn is below 200 after untwisting. The untwisted yarn islinear and its fibers are parallel. The density of the fabric is between60-800 pieces per 10 CM. The fabric, whose air porosity andhygroscopicity could reach the best state if whose density is between 60and 150 pieces per 10 CM, but the stereoscopy and the strength are notgood. The better density is between 220 and 500 pieces per 10 CM, inthis case, the fabric will have the better stereoscopy and the crispaesthetics, also have softness, air porosity, hygroscopicity and thesmooth surface. If the density of the fabric is between 500 and 900pieces per 10 CM, the stereoscopy will be the best, but the air porosityand the softness are not good. In order to increase the strength of thefabric and ensure the fabric to have bulkiness, comfort, hygroscopicity,air porosity, we let the quality of the twisted yarns 4 be more than orequal to the quality of the untwisted yarns 3. In order to increase thesoftness, air porosity, hygroscopicity, bulk for the fabric and ensurethe fabric to have better strength, the diameter of the untwisted yarnis designed to be 1.1-5 times the size of the diameter of the previoustwisted one, and the density of the fabric is between 200 and 480 piecesper 10 CM. The better program: the diameter of the fabric is 1.1-2 timesthe size of the diameter of the previous twisted one, and the density ofthe fabric is between 150 and 500 pieces per 10 CM. The present utilitymodel provides the first program, with which the stereoscopy and thecrisp aesthetics will be enhanced for the fabric. The first program: thewarp yarns are twisted yarns, the weft yarns are untwisted yarns, thatthe quality of twisted warp yarns is smaller than the quality ofuntwisted weft yarns; the warp yarns are untwisted yarns, the weft yarnsare twisted yarns, that the quantity of the twisted weft yarns issmaller than the quantity of the untwisted warp yarns. The presentutility model provides the better program: the twisted yarns and theuntwisted yarns are arranged one by one to form warp yarns, the twistedyarns and the untwisted yarns are arranged one by one to form weftyarns; the twisted yarns and the untwisted yarns are arranged one by oneto form warp yarns, the untwisted yarns are weft yarns; the twistedyarns and the untwisted yarns are arranged one by one to form the weftyarns, the untwisted yarns are warp yarns. The density of the fabric isbetween 220 and 400 pieces per 10 CM. The present utility model providesthe perfect fabric in this area, which has the air porosity, softness,hygroscopicity, bulkiness, heat retention and crisp aesthetics.
